Doctor Frank-N-Furter (A mad scientist) Frank-N-Furter is just a "sweet Transvestite, from Transsexual, Transylvania." He lives in a castle just outside Denton with his handyman, Riff Raff, domestic (sister of Riff Raff) Magenta and groupie, Columbia. He is a mad scientist and a bi man- he just likes . His most recent (and only known) creation is a muscular and handsome man named Rocky Horror. Frank is the most eccentric character, and his humor is often twisted and crude. He is not afraid to kill anyone (or eat them, for that matter!) as he killed Eddie, his ex-delivery boy and test subject.
